Abstract
To verify that a communications path restored in response to a failure to a telecommunications network is a validly restored path, each of the end nodes terminating the restored communications path sends out a message containing data that identifies that node and the ID of the access/egress port to which the STS-1 circuit forming the communications path is connected. Once the respective path verification messages are exchanged between the two end nodes of the communications path, the Operations Support System (OSS) that oversees the topology of the network retrieves those messages and compares the data contained therein with the data of the same type of messages from the same ends nodes that were stored just prior to the occurrence of the disruption to the communications path. The restored communications path is deemed to be verified if there are no differences between the path verification messages retrieved after the failure event and the path verification messages stored just prior to the failure event.
